DETROIT -- Lost in the shuffle of a handful of roster moves made Tuesday was the rise and fall of right-handed reliever Robbie Weinhardt.

Less than two months ago, Weinhardt was a favorite to win a bullpen job out of spring training. On Tuesday, he was designated for assignment after giving up four earned runs in two-thirds of an inning Monday for Triple-A Toledo.

The move was made in order to make room for left-handed reliever Adam Wilk on the Tigers' 40-man roster. The club has 10 days to trade, release or reassign him to the Minor Leagues. Speculation suggests Weinhardt will likely be plucked by another organization.

Weinhardt made a couple appearances earlier this season in Detroit, but was eventually optioned to Triple-A Toledo on April 12. His struggles continued in Toledo, allowing 18 runs in 15 1/3 innings en route to an 8.80 ERA in 13 games.

Tigers manager Jim Leyland attributed Weinhardt’s free fall to an ineffective sinker -- considered to be the 25-year-old’s bread-and-butter pitch.

“I don’t know if he lost his sinker, as much as he just left the sinker up to much,” Leyland said. "And, high sinkers just aren't good."

Prior to the season, Leyland said Weinhardt had improved his slider by throwing it more often during winter ball games in Puerto Rico and considered him “sharp” the first couple weeks of spring training.
